Aline passes through 2, -1 and 4, 5 what is the equation

y1 - y2 / x1 - x2

-1 - 5 / 2 - 4

-6/-2

3

y = mx + b

-1 = 3(2) + b

-1 = 6 + b

-7 = b

y = 3x - 7

Hope this helps! ;)

The equation is

Solution:

Let us assume that the and

The slope of the line m is

We know the equation of a line at a given point

Let me take the point (4,5) here,

So the equation of the line is  

So, the equation is

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
